Supported File Types

Private AI can support multiple file types for de-identification. The complete list of supported file types is below. New file types are continually being added, please contact us if you require a file type not in the list below.

Private AI’s supported entity types function across each file type, with multilingual equivalents of different PII (Personally Identifiable Information) entities, PHI (Protected Health Information) entities, and PCI (Payment Card Industry) entities being detected. Our Supported Entity Types page provides a more detailed look at entities.

Supported Languages

Note that while Private AI text de-identification service supports more than 50 languages, the file processing service supports a restricted list of languages. See supported languages for more details.

VOX files

.vox files are not natively supported in the Private AI container, but can be processed by converting the .vox file to a wav or mp3 using a conversion tool like SoX

Because .vox files are headerless, you will need to know the sample rate and encoding to specify.

For example, to take a vox file with a sample rate 8000, mono channel, mu-law encoded: sox -t raw -r 8000 -c 1 -e mu-law myfile.vox myfile.wav

to generate a wav file.
